Docs/mm/damon/faq: remove old questions

Patch series "Docs/mm/damon: Minor fixes and design doc update".

Some of the DAMON documents are outdated, or having minor typos or grammar
erros.  Especially, the design doc has not updated for DAMOS, which is an
important part of DAMON.  Fix the minor issues and update documents.


This patch (of 10):

The first two questions of DAMON faqs have raised when DAMON patches were
first submitted.  More than one year has passed since DAMON patches get
merged in the mainline, and that kind of questions are not asked nowadays.
Remove the questions.
